UNITED STATES ALEXANDER T. BROWN, OF SYR-ACUSE, NEW YORK.

TRACTOR P'Low.

Application filed October 21, 1919. Serial No. 332,218.

To ZZ wimmz't may concern Be it known that l, ALEXANDER "l". BROWN,

a citizen of the United States, and a resident of Syracuse, in thecounty of Onondaga and State of New York,have invented a newV and usefulTractor Plow, of which the following is a specilication.

rl`his invention relates to tractors or motor agricultural machines andhas for its object a particularly simple and efficient arrangement oithe implements, Vas -plows, relatively to the plowing and to the frameor chassis of the machine and also a. particularly simple and eHicientmeansreadily-ap' plicable to tractors for raising and lowering theimplements, as plows. Other objects will appear throughout thespecification.

rilhe invention consistsin the novel features and in the combinationsand constructions hereinafter set forth and claimed.

ln describing this invention, reference is had to the accompanyingdrawings in which like characters desifnate corresponding parts in allthe views.k

Figure i is a plan view of the tractor at different points inpositioning` at the end of a turrow embodying my invention, parts beingomitted, two of the positions occupied thereby while positioning at theend ot the furrow being shown in dotted lines. p Figure 2 is a sidevelevation thereof. Figure 3 is a plan view of parts seenin Fi 2.

Figure 16 is a detail view oi' the connec-l tions betweenone side sillof the tractor chassis andthe truck framesupporting` the raised tractorbelt mechanism. Y

Figure i7 'is a fragmentary seen in Fig. i6.

Figure 1S is a fragmentary detail sectional view taken approximately online is-is, rig-.15.

This invention comprises, generally, a tractor chassis having tractorwheels or belts on opposite sidesy thereof, implements, plows,projecting or oif'erhanging from the front and rear ends of trie chassisiframe, the implements at either end and lowering those at the other` orfor raising the implements at both ends The chassis includes a frame ofany suitable orm, size and construction, which comprises generally, sidesills l and cross bars, truck frames and tractor belt mechanismsupported by the trucki'rame's.

Each truck frame comprises parallel bars 3, at connected at their frontends by a yoke plan ot parts 5, Figs. l2, lt, and l5, the bars 8, lsupporting bearings v6, 7 for front and rear axles for the wheels aroundwhich the right and left tractor belts S, 9 run. Each truck frame alsoincludes framing lO for supp-ortingV the idler wheels 1l which hold thelower runs ot' the belts straight. Y

The left hand tractor belt frame (considered when the observer is on theseat looking forwardly) is higher than the right hand as the left handbelt and always runs on the unplowed land, and the right hand belt runsin the furrow and is held by the urro f in its course so that itautomatically steers the machine. he i'ront and rear axles for the righttractor belt mechanism are designated l2 and 13 respectively and thosefor the lett hand 'la and l5 respectively. rl'he bearings 7 for the rearaxles i3, l5. are carried by the chassis, and the front axles 12, i4 arecarried in the bearings 5 which are supported by the bars 3, The bars 3,

4 are spring supported at their front ends by a spring 16 which isconnected to the yokes 5 by shackles 17, 18, the shackle 18 connected tothe higher' lei't hand truck ,trame being longer than the shackle 17.

The higher left hand tractor belt, truck and mechanism is also locatedslightly ahead of the lower right hand belt truck, and the rear axle 13thereof is located directly below the driving mechanism located in thecasing 19, Fig. 13, and the rear axle 15 in front of said mechanism.Thus the axles 13, 15. are located in different vertical and horizontalplaneswithrespect to the driving shaft sections in the casing 19 for apurpose to be hereinafter described. VThe front axles 12, 14 aresimilarly located. The rear axle 13 is carried on the lower side of theright hand side sill or an extension thereof, and the rear axle 15 onthe upper side of lett hand sill or extension thereof. The rear axle 13is clamped between bearing sections 13, 13b, the lower sections 13bbeing removable, and the axle 15 is interchangeable from itsk positionshown into position indicated lin dotted lines, Fig. 13 where it is heldbetween similar Vbearings 13, 13d.

The front portion of the truck frames are connected to the sills of thechassis to permit up and down movement duringr the action of the spring`16 by guides 20, Figs. 14, 15, 16 and 17 secured at 21 to the truckframes and having vertical portions as 22 moving through eyes or slotsin the contiguous bracket, the vertical portion 22 of the right handbracket, that is, the bracket at the right hand of the machine whenlooking forwardly from the seat moves through an eye or slot 23 in thebracket 24 mounted on therighthand sill 3, the eye or slot 23 substantially fitting the vertical portion 22. The slot 23a in the bracket24a for the higher left handbelt are long enough to permit a forwardmovement of the adjacent guide 2O when the left hand belt is shifted tobe on a level with the right hand belt.

26, 27 and 28, 29. are the frontand rear sprocket wheels around whichthe tractor belts run mounted on the axles 12, 13 and 14, 15respectively and the rear sprockets are formed with internal gears 30, 31 with which mesh pinions 32, 33 mounted on shaft sections 34, extendingwithin thecasing 19. i l

'The shaft sections 34, 35 are arranged in line and connected by thedifferential gearing in the casing 19 but owingl to `the fact that theaxles 13, 15 Vfor the wheels 27. 29 are arranged out ot alinement, thepinions 32, mesh with the internal gears 30, `31 of the wheels 27, 29 atrelatively different points, although theV shaft sections 35 on whichthe pinions are mounted are arranged in alinement. As seen in the pinion32 meshes with the internal gear 30 directly .tor wheels including theshaft sections 34,

above'in a vertical radius of the axle 13 while the pinion 33 mesheswith its internal gear 31 in rear of and along a horizontal radius ofthe axle 15.

36designates the power plant as a whole, mounted on the chassis andincluding an internal combustion engine'located under the hood 36a andsuitable power transmitting mechanism between the engine and the trac-35 and the diiferential gearing in the casing 19 connectingsaidsections. i

The implementshereshown as .plows, or plow bodies 37., 38 carried bysupports, as beams 39, 39") movably connected to the frame 1 oithetractor and as hereshown, the beams are pivoted Vat39n to bracketsmounted olrthe `ends of the sills of the traine 1. v

The .plows 37 ,and 33ers reversely arranged with respect to .each.other,.that is, the `plows 37 are constructed to turn right handfurrows and the ,plows 38 to turn left hand furrowsand as 4here shown,there a gang of two plows overhanging from each end ot ythe trame 1.

The means forzraising and lowering the plows 37, 38 is operable at willthrough con nections with the; power plant or crank shaft of the engineand as here shown, these connections comprise a rotary element as adrive shaft 40. located at one end, as the front end ofthe chassis infront ot' the power plant having cranks 4l at its opposite ends,connections between yeach crank and the front and rear plows, and meansconnectible at will to the engine, whereby the shaft 40 yis moved aboutits axis.

The shaft 40-is here shown as mounted in bearings 42carricd by the upperends of a pair of arms 43, 44 at each side of the frontl end .of theframe, each arm 44 being pivoted at 45 to a bracket 46 mounted on thefront end of one ofv the sills of the frame 1 each arm 44 having abearing 44a at its upper end around one of thebearings 42 for the shaft40. Each arm 43 is pivoted at its lower end at 47 to a bracket 48 on theside sill of the chSsis and has` its upper end pivoted at 49 to an arm50 on the bearing 44a. The arm 43 `is located in therear of the arm 44and converges upwardly toward the arm 44. The bracketsfelt hai'efinlnrality oipairs oi' .openings 51 in ,A pair ot which the pivotsflgofthe plow .i beams 39, V39b maybe located. A

-The hearings 42 are termed at the yopi site ends oi a tubular c @W105in shaftA 40, The crank ,arms 1 are con i to the plows 37 or to the beams39 thereof by means ci? suitable "flexible power transmit tingconnectionsas .cables 53, each cae` i ing a llink 54at one end-haring abear' the crank pin 56 of one of the crank arms 41 and having its otherend secured to the plow beam. The plows 37 at the rear end of the frameare operated Yfrom t-he same crank arms 41 as the plows yat the frontend through links 57 extending lengthwise of the chassis' and havingbearings at their front ends on the crank pins 56 and connected at theirrear ends at 58 to the upper ends of the arms 59 which are pivoted at 60to brackets 61 on the rear end of the frame to which brackets 61 arealso pivoted, the plow beams 39 of the rear plows. The arms 59 areConnected to the plows 37 by cables`62 similar to cables 53. Each pairof plow beams 39 or 39b are fixed to a single bracket 63 or64 having abearing upon the corresponding pivot-s or shafts 39a so that each pairof plows is raised and lowered as a unit. Y

The means for actuating the shaft 40 as here shown, comprises a drivingelement, as asharft 65 having' a worm 66 thereon which meshes with thedriven worm wheel 67 mounted on the shaft 40, the shaft 65 being drivenfrom the engine, as will be presently described. This shaft 65 isliournaled in bearings formed in and suitably supported by the casing 52and it is held from movement relatively to the shaft 40 by means ofbrace rods 68 connecting the arms 44, these rods eirtending through apassage 69 formed in the lower side of thefcasing 52. After the positionof the casing 52 has been determined to line up the belt 71, the arms orrods 68 are secured to the casing by means of a set screw 70. i

The shaft 65 .is connected to the crank shaft of the engine by anysuitable meanshere shown las a belt 71 running over pulleys 72 and 7 3mounted respectively on thev shaft 65 and the crank shaft of the engineand this belt is normally loose so that it transmits no power. It may betightened at will by means of an idler 72EL coacting with theV belt andcarried bythe arm 73EL mounted on a rock shaft 74 which is operable by asuitablerpedal 75 carried by the frame within reach of the seat 76 andconnected to the arm 73fL through suitable links and levers 77. 7 ,Y Y

In applying the plows and the raising and loweringmechanism to tractorsthe arms 43 and 44 with the bracketsV at the lower ends thereof aremounted on the side sills of the frame or extension thereof and thepulley 7 3 mounted on the crank shaft; the upper pul-` ley 72 can belocated in vertical alinement with the lower pulley 73 by'swinging theyarms 43 or 44 und the shaft 40 forwardly or rearwardly and thentightening the set screw and lock nut 70a on a shim of suitablethickness at 70b to get vertical alinement; and the plow beams. or thebrackets connecting` the ends thereof are mounted on a shaft. supportedby the same brackets on which the arms 44 are mounted.

Tractors havingtractor belts are usually steered by slowing or speedingup the belt i on one side relatively toY the belt on the other. Whensuch tractors are pulling` the torque reaction' causes the frontendofthe tractor to lift up more orfless.

Owing to the arrangement of the imple-l ments or plows atboth ends ofthe tractorv as provided by my invention, the implements out of theground tend to counterbalance the reaction and hold one end -of thetractor from lifting, and furthermore, owing to the arrangement of thetractor belts in different planes,the tractor stands level as one of thetractor belts runs in the furrow previously cut. Also, when plowing thetractor is self steering as the belt running in the furrow steers thetractor.

yIn operation, during the travel of the machine across the field, as tothe right in Fig. 1 as indicated by the full lines at A, the rear plows37 are lowered and the front plows 38 elevated and as the end' of thefurrow is reached, Athe tractor is turned to the left or upwardly inFig. l into the position indicated in dotted lines at B at the right endof F ig. 1, so that the right hand tractor belt 8 will come on its wayback, into the last furrow just cut. Theplows 37 at the rear end of thetractor are elevated and the plows 38 at the frontend at C lowered afterthe tractor starts back across the'field and the plows 38 come to theend of the furrows turned by the plows .38 when in position A. As theplows 38 at the front end turn left hand furrows, the furrows now beingcut by the plows 38 will be the same as those cut by the plows 37'during the preceding trip across the field. The plows are dropped as atC so'that the furrows Vwill be even at their In moving" the tractor toand from the field and in manipulating it about the field, both frontand rear plows are elevated into the position shown in Fig. (il

To elevate Aand lower the plows the operator depresse's the pedal 75 tocause the idler 72 to tighten thev belt 71 and act to.,v clutch the wormshamt 65 to the crank shaft ofthe engine throughthe pulley 73,'belt 71and pulley 70. During the'rotation of the worm shaft 65'the worm gear 67is rotated, which in turn rotates the shaft 40. When the crank arms 41are inV one radial position, as shown in Fig. 4, the rear plows 7 arelowered into plowing position and the front plows 38 elevated. When theshaft 40 is rotated to carry the crank arms 41 into the position shownin Fig. 5, the plows 38 at the fronk end are lowered into plowingposition and plows 37 at the rear end are elevated and when said shaft40 is rotated to carry the crank arms 41 into the angular position shownin Fig. 6 the plows 37, 38 at both the front and rear ends are elevatedabove the ground.
